Hateful. Further, it is very difficult to uniformly coat a sheet having an uneven pattern on the surface. When the coating film is thick, the solvent attack on the vinyl chloride resin sheet, styrene resin sheet and acrylic resin sheet is strong, which is practically difficult. Therefore, it is difficult to uniformly and economically provide a vinylidene fluoride resin layer on the surface of the vinyl chloride resin sheet, the styrene resin sheet and the acrylic resin sheet by any of the methods.
